* ext4: Rework the ext4_da_writepages() functionAneesh Kumar K.V2008-08-19
| | | | | | | | | | | | | | | | | | | | With the below changes we reserve credit needed to insert only one extent resulting from a call to single get_block. This makes sure we don't take too much journal credits during writeout. We also don't limit the pages to write. That means we loop through the dirty pages building largest possible contiguous block request. Then we issue a single get_block request. We may get less block that we requested. If so we would end up not mapping some of the buffer_heads. That means those buffer_heads are still marked delay. Later in the writepage callback via __mpage_writepage we redirty those pages. We should also not limit/throttle wbc->nr_to_write in the filesystem writepages callback. That cause wrong behaviour in generic_sync_sb_inodes caused by wbc->nr_to_write being <= 0 Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Reviewed-by: Mingming Cao <cmm@us.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* ext4: journal credits reservation fixes for DIO, fallocateMingming Cao2008-08-19
| | | | | | | | | | | | | | | | | | | DIO and fallocate credit calculation is different than writepage, as they do start a new journal right for each call to ext4_get_blocks_wrap(). This patch uses the helper function in DIO and fallocate case, passing a flag indicating that the modified data are contigous thus could account less indirect/index blocks. This patch also fixed the journal credit reservation for direct I/O (DIO). Previously the estimated credits for DIO only was calculated for non-extent files, which was not enough if the file is extent-based. Also fixed was fallocate double-counting credits for modifying the the superblock.

* ext4: journal credits reservation fixes for extent file writepageMingming Cao2008-08-19
| | | | | | | | | | | | | | | | | This patch modified the writepage/write_begin credit calculation for extent files, to use the credits caculation helper function. The current calculation of how many index/leaf blocks should be accounted is too conservetive, it always considered the worse case, where the tree level is 5, and in the case of multiple chunk allocations, it always assumed no blocks were dirtied in common across the allocations. This path uses the accurate depth of the inode with some extras to calculate the index blocks, and also less conservative in the case of multiple allocation accounting.

* ext4: journal credits calulation cleanup and fix for non-extent writepageMingming Cao2008-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | When considering how many journal credits are needed for modifying a chunk of data, we need to account for the super block, inode block, quota blocks and xattr block, indirect/index blocks, also, group bitmap and group descriptor blocks for new allocation (including data and indirect/index blocks). There are many places in ext4 do the calculation on their own and often missed one or two meta blocks, and often they assume single block allocation, and did not considering the multile chunk of allocation case. This patch is trying to cleanup current journal credit code, provides some common helper funtion to calculate the journal credits, to be used for writepage, writepages, DIO, fallocate, migration, defrag, and for both nonextent and extent files. This patch modified the writepage/write_begin credit caculation for nonextent files, to use the new helper function. It also fixed the problem that writepage on nonextent files did not consider the case blocksize <pagesize, thus could possibelly need multiple block allocation in a single transaction.

* ext4: Fix bug where we return ENOSPC even though we have plenty of inodesEric Sandeen2008-08-19
| | | | | | | | | | | | | | | | | | | | | The find_group_flex() function starts with best_flex as the parent_fbg_group, which happens to have 0 inodes free. Some of the flex groups searched have free blocks and free inodes, but the flex_freeb_ratio is < 10, so they're skipped. Then when a group is compared to the current "best" flex group, it does not have more free blocks than "best", so it is skipped as well. This continues until no flex group with free inodes is found which has a proper ratio or which has more free blocks than the "best" group, and we're left with a "best" group that has 0 inodes free, and we return -ENOSPC. We fix this by changing the logic so that if the current "best" flex group has no inodes free, and the current one does have room, it is promoted to the next "best."

* ext4: don't try to resize if there are no reserved gdt blocks leftJosef Bacik2008-08-19
| | | | | | | | | | | | | | | When trying to resize an ext4 fs and you run out of reserved gdt blocks, you get an error that doesn't actually tell you what went wrong, it just says that the gdb it picked is not correct, which is the case since you don't have any reserved gdt blocks left. This patch adds a check to make sure you have reserved gdt blocks to use, and if not prints out a more relevant error.

* ext4: Fix delalloc release block reservation for truncateMingming Cao2008-08-19
| | | | | | | | | | | | | | | | | | Ext4 will release the reserved blocks for delayed allocations when inode is truncated/unlinked. If there is no reserved block at all, we shouldn't need to do so. But current code still tries to release the reserved blocks regardless whether the counters's value is 0. Continue to do that causes the later calculation to go wrong and a kernel BUG_ON() caught that. This doesn't happen for extent-based files, as the calculation for 0 reserved blocks was right for extent based file. This patch fixed the kernel BUG() due to above reason. It adds checks for 0 to avoid unnecessary release and fix calculation for non-extent files. Signed-off-by: Mingming Cao <cmm@us.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

* | | fs: rename buffer trylockNick Piggin2008-08-05
| | | | | | | | | | | | | | | | | | | | | | | | Like the page lock change, this also requires name change, so convert the raw test_and_set bitop to a trylock. Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | | mm: rename page trylockNick Piggin2008-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Converting page lock to new locking bitops requires a change of page flag operation naming, so we might as well convert it to something nicer (!TestSetPageLocked_Lock => trylock_page, SetPageLocked => set_page_locked). This also facilitates lockdeping of page lock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f9247273cb69ba101877e946d2d83044409cc8c5 (and fb2e405fc1fc8b20d9c78eaa1c7fd5a297efde43 - "fix fs/nfs/nfsroot.c compilation" - that fixed a missed conversion). The changes cause problems for at least the sparc build. Let's re-do them when the exact issues are resolved.

So add seperate functions to be used in the truncate and alloc path. We also need to release the meta-data block that we reserved for the blocks that we are truncating.
