Here's a bunch of shmem/tmpfs updates: mostly completed in January, then put aside while I attended to other stuff. But the more recent 1/10 has some urgency, so I'm expediting the descriptions, and shipping them off to you now for v3.5. They're diffed against 3.4.0-rc5-next-20120504, but apply and build and work on most v3.4-rc and v3.4-rc-next. The fallocate ones were prompted by posts from Cong Wang in November: I've attributed four of those with Based-on-patch-by, but could not put From or Signed-off-by, since the originals were somewhat flawed, and I needed to start again and reorder it all. Whether 10/10 should go any further than exposure in -next is in doubt: we shall have to see if it's useful to anyone. 1/10 shmem: replace page if mapping excludes its zone 2/10 tmpfs: enable NOSEC optimization 3/10 tmpfs: optimize clearing when writing 4/10 tmpfs: support fallocate FALLOC_FL_PUNCH_HOLE 5/10 mm/fs: route MADV_REMOVE to FALLOC_FL_PUNCH_HOLE 6/10 mm/fs: remove truncate_range 7/10 tmpfs: support fallocate preallocation 8/10 tmpfs: undo fallocation on failure 9/10 tmpfs: quit when fallocate fills memory 10/10 tmpfs: support SEEK_DATA and SEEK_HOLE Documentation/filesystems/Locking | 2 Documentation/filesystems/vfs.txt | 13 drivers/staging/android/ashmem.c | 8 fs/bad_inode.c | 1 include/linux/fs.h | 1 include/linux/mm.h | 4 include/linux/swap.h | 6 mm/madvise.c | 15 mm/memcontrol.c | 17 mm/shmem.c | 513 +++++++++++++++++++++++++--- mm/swapfile.c | 2 mm/truncate.c | 25 - 12 files changed, 500 insertions(+), 107 deletions(-) Hugh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
