2012-01-09reiserfs: Force inode evictions before umount to avoid crashJeff Mahoney
This patch fixes a crash in reiserfs_delete_xattrs during umount. When shrink_dcache_for_umount clears the dcache from generic_shutdown_super, delayed evictions are forced to disk. If an evicted inode has extended attributes associated with it, it will need to walk the xattr tree to locate and remove them. But since shrink_dcache_for_umount will BUG if it encounters active dentries, the xattr tree must be released before it's called or it will crash during every umount. This patch forces the evictions to occur before generic_shutdown_super by calling shrink_dcache_sb first. The additional evictions caused by the removal of each associated xattr file and dir will be automatically handled as they're added to the LRU list.

2012-01-09udf: Fix deadlock when converting file from in-ICB one to normal oneJan Kara
During BKL removal in 2.6.38, conversion of files from in-ICB format to normal format got broken. We call ->writepage with i_data_sem held but udf_get_block() also acquires i_data_sem thus creating A-A deadlock. We fix the problem by dropping i_data_sem before calling ->writepage() which is safe since i_mutex still protects us against any changes in the file. Also fix pagelock - i_data_sem lock inversion in udf_expand_file_adinicb() by dropping i_data_sem before calling find_or_create_page().

2012-01-09ext2: Fix error handling on inode bitmap corruptionJan Kara
When insert_inode_locked() fails in ext2_new_inode() it most likely means inode bitmap got corrupted and we allocated again inode which is already in use. Also doing unlock_new_inode() during error recovery is wrong since the inode does not have I_NEW set. Fix the problem by informing about filesystem error and jumping to fail: (instead of fail_drop:) which doesn't call unlock_new_inode().

2012-01-09ASoC: cx20442: add bias control over a platform provided regulatorJanusz Krzysztofik
Now that a regulator device for controlling the codec chip reset state over a platform agnostic regulator API is available on the only board using this driver so far, extend the driver with a bias control function which will request virtual power to the codec chip from that virtual regulator, and will supersede the present implementation existing at the sound card level. Thanks to the regulator sharing mechanism, both the old (the sound card) and the new (the codec) implementations should coexist smoothly until the sound card file is updated. For this to work as expected, update the sound card .set_bias_level callback to not touch codec->dapm.bias_level. While extending the cx20442 structure, drop unused control_type member. Created against linxu-3.2-rc6, tested on top of patch 1/4 "ARM: OMAP1: ams-delta: set up a regulator over the modem reset GPIO pin".
