2017-07-27xen: dont fiddle with event channel masking in suspend/resumeJuergen Gross
Instead of fiddling with masking the event channels during suspend and resume handling let do the irq subsystem do its job. It will do the mask and unmask operations as needed.

2017-07-27xen: selfballoon: remove unnecessary static in frontswap_selfshrink()Gustavo A. R. Silva
Remove unnecessary static on local variables last_frontswap_pages and tgt_frontswap_pages. Such variables are initialized before being used, on every execution path throughout the function. The statics have no benefit and, removing them reduce the code size.

2017-07-27NFS: Optimize fallocate by refreshing mapping when needed.NeilBrown
posix_fallocate() will allocate space in an NFS file by considering the last byte of every 4K block. If it is before EOF, it will read the byte and if it is zero, a zero is written out. If it is after EOF, the zero is unconditionally written. For the blocks beyond EOF, if NFS believes its cache is valid, it will expand these writes to write full pages, and then will merge the pages. This results if (typically) 1MB writes. If NFS believes its cache is not valid (particularly if NFS_INO_INVALID_DATA or NFS_INO_REVAL_PAGECACHE are set - see nfs_write_pageuptodate()), it will send the individual 1-byte writes. This results in (typically) 256 times as many RPC requests, and can be substantially slower. Currently nfs_revalidate_mapping() is only used when reading a file or mmapping a file, as these are times when the content needs to be up-to-date. Writes don't generally need the cache to be up-to-date, but writes beyond EOF can benefit, particularly in the posix_fallocate() case. So this patch calls nfs_revalidate_mapping() when writing beyond EOF - i.e. when there is a gap between the end of the file and the start of the write. If the cache is thought to be out of date (as happens after taking a file lock), this will cause a GETATTR, and the two flags mentioned above will be cleared. With this, posix_fallocate() on a newly locked file does not generate excessive tiny writes. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
2017-07-27NFS: invalidate file size when taking a lock.NeilBrown
Prior to commit ca0daa277aca ("NFS: Cache aggressively when file is open for writing"), NFS would revalidate, or invalidate, the file size when taking a lock. Since that commit it only invalidates the file content. If the file size is changed on the server while wait for the lock, the client will have an incorrect understanding of the file size and could corrupt data. This particularly happens when writing beyond the (supposed) end of file and can be easily be demonstrated with posix_fallocate(). If an application opens an empty file, waits for a write lock, and then calls posix_fallocate(), glibc will determine that the underlying filesystem doesn't support fallocate (assuming version 4.1 or earlier) and will write out a '0' byte at the end of each 4K page in the region being fallocated that is after the end of the file. NFS will (usually) detect that these writes are beyond EOF and will expand them to cover the whole page, and then will merge the pages. Consequently, NFS will write out large blocks of zeroes beyond where it thought EOF was. If EOF had moved, the pre-existing part of the file will be over-written. Locking should have protected against this, but it doesn't. This patch restores the use of nfs_zap_caches() which invalidated the cached attributes. When posix_fallocate() asks for the file size, the request will go to the server and get a correct answer. cc: stable@vger.kernel.org (v4.8+) Fixes: ca0daa277aca ("NFS: Cache aggressively when file is open for writing") Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
