2011-01-06net: add POLLPRI to sock_def_readable()Eric Dumazet
Leonardo Chiquitto found poll() could block forever on tcp sockets and Urgent data was received, if the event flag only contains POLLPRI. He did a bisection and found commit 4938d7e0233 (poll: avoid extra wakeups in select/poll) was the source of the problem. Problem is TCP sockets use standard sock_def_readable() function for their sk_data_ready() handler, and sock_def_readable() doesnt signal POLLPRI. Only TCP is affected by the problem. Adding POLLPRI to the list of flags might trigger unnecessary schedules, but URGENT handling is such a seldom used feature this seems a good compromise. Thanks a lot to Leonardo for providing the bisection result and a test program as well.

2011-01-06kernel-doc: code reorganizationRandy Dunlap
Move 'main' code vs. subroutines around so that they are not so intermixed, for better readability/understanding (relative to Perl). It was messy to follow the primary flow of code execution with the code being mixed. Now the code begins with data initialization, followed by all subroutines, then ends with the main code execution. This is almost totally source code movement, with a few changes as needed for forward declarations.

2011-01-06UDF: Close small mem leak in udf_find_entry()Jesper Juhl
Hi, There's a small memory leak in fs/udf/namei.c::udf_find_entry(). We dynamically allocate memory for 'fname' with kmalloc() and in most situations we free it before we leave the function, but there is one situation where we do not (but should). This patch closes the leak by jumping to the 'out_ok' label which does the correct cleanup rather than doing half the cleanup and returning directly.

2011-01-06udf: Fix directory corruption after extent mergingJan Kara
If udf_bread() called from udf_add_entry() managed to merge created extent to an already existing one (or if previous extents could be merged), the code truncating the last extent to proper size would just overwrite the freshly allocated extent with an extent that used to be in that place. This obviously results in a directory corruption. Fix the problem by properly reloading the last extent. Signed-off-by: Jan Kara <jack@suse.cz>
2011-01-06udf: Protect udf_file_aio_write from possible racesJan Kara

The udf_readdir(), udf_lookup(), udf_create(), udf_mknod(), udf_mkdir(), udf_rmdir(), udf_link(), udf_get_parent() and udf_unlink() seems already adequately protected by i_mutex held by VFS invoking calls. The udf_rename() instead should be already protected by lock_rename again by VFS. The udf_ioctl(), udf_fill_super() and udf_evict_inode() don't requires any further protection.

2011-01-06udf: Remove BKL from free space counting functionsJan Kara
udf_count_free_bitmap() does not need BKL because bitmaps are in a fixed place on disk and so we can count set bits without serialization. udf_count_free_table() is now protected by s_alloc_mutex instead of BKL to get a consistent view of free space extents. Signed-off-by: Jan Kara <jack@suse.cz>
2011-01-06udf: Call udf_add_free_space() for more blocks at once in udf_free_blocks()Jan Kara
There's no need to call udf_add_free_space() for one block at a time. It saves us noticeable amount of work and yields different result from the original code only if the filesystem is corrupted and bitmap bit is already cleared. In such case counter of free blocks is probably wrong anyways so the change does not matter. Signed-off-by: Jan Kara <jack@suse.cz>
2011-01-06udf: Remove BKL from udf_put_super() and udf_remount_fs()Jan Kara
udf_put_super() does not need BKL because the filesystem is shut down so there's nothing to race with. The credential changes in udf_remount_fs() and LVID changes are now protected by dedicated locks so we can remove BKL from this function as well. Signed-off-by: Jan Kara <jack@suse.cz>
2011-01-06udf: Protect default inode credentials by rwlockJan Kara
Superblock carries credentials (uid, gid, etc.) which are used as default values in __udf_read_inode() when media does not provide these. These credentials can change during remount so we protect them by a rwlock so that each inode gets a consistent set of credentials. Signed-off-by: Jan Kara <jack@suse.cz>
2011-01-06udf: Protect all modifications of LVID with s_alloc_mutexJan Kara
udf_open_lvid() and udf_close_lvid() were modifying LVID without s_alloc_mutex. Since they can be called from remount, the modification could race with other filesystem modifications of LVID so protect them by s_alloc_mutex just to be sure. Signed-off-by: Jan Kara <jack@suse.cz>
2011-01-06udf: Move handling of uniqueID into a helper function and protect it by a ↵Jan Kara
s_alloc_mutex uniqueID handling has been duplicated in three places. Move it into a common helper. Since we modify an LVID buffer with uniqueID update, we take sbi->s_alloc_mutex to protect agaist other modifications of the structure. Signed-off-by: Jan Kara <jack@suse.cz>
2011-01-06udf: Remove BKL from udf_update_inodeJan Kara
udf_update_inode() does not need BKL since on-disk inode modifications are protected by the buffer lock and reading of values of in-memory inode is safe without any lock. In some cases we can write inconsistent inode state to disk but in that case inode will be marked dirty and overwritten later. Also make unnecessarily global udf_sync_inode() static.

2011-01-06UBI: use mtd->writebufsize to set minimal I/O unit sizeAnatolij Gustschin
Previously we used mtd->writesize field to set UBI's minimal I/O unit size. This sometimes caused UBIFS recovery issues when mounting an uncleanly unmounted UBIFS partition on NOR flash since mtd->writesize is 1 byte for NOR flash. The MTD CFI driver however often performs writing multiple bytes in one programming operation using the chip's write buffer. We have to use the size of this write buffer as a minimal I/O unit size for UBI on NOR flash to fix the observed UBIFS recovery issues.

2011-01-06mtd: add writebufsize field to mtd_info structAnatolij Gustschin
This field will be used to indicate the write buffer size of the MTD device. UBI will set it's minimal I/O unit size (min_io_size) to the indicated write buffer size. By this change we intend to fix failed recovery of UBIFS partitions we currently observe on NOR flash when mounting the partition after unclean unmount. Currently the min_io_size is set to mtd->writesize (which is 1 byte for NOR flash). But flash programming is often done from prepared write buffer containing multiple bytes and is performed in one programming operation which could be interrupted by a power cut or a system reset causing corrupted (partially written) areas in a flash sector. Knowing the size of potentially corrupted areas UBIFS scanning and recovery algorithms are able to perform successful recovery. In case of NOR flash minimal I/O size must be equal to the maximal size of the write buffer used by embedded flash programming algorithm. In case of NAND flash mtd->writebufsize should be equivalent to mtd->writesize. The subsequent patches will add mtd->writebufsize initialization where needed.

2011-01-06mtd: nand: ams-delta: drop omap_read/write, use ioremapJanusz Krzysztofik
There is a common requirement for not using OMAP specific omap_readw() / omap_writew() function calls in drivers/, but replace them with readw() / writew() on ioremap()ped addresses passed from arch/ instead. The patch implements this idea for the Amstrad Delta NAND driver. To be able to use the modified driver, the board file is updated with the platform device I/O resource declaration, which is passed from there. Created and tested against linux-2.6.37-rc5, on top of recent patch 'MTD: NAND: ams-delta: convert to platform driver'.
