2013-04-30nfsd4: don't remap EISDIR errors in renameJ. Bruce Fields1-15/+5
We're going out of our way here to remap an error to make rfc 3530 happy--but the rfc itself (nor rfc 1813, which has similar language) gives no justification. And disagrees with local filesystem behavior, with Linux and posix man pages, and knfsd's implemented behavior for v2 and v3. And the documented behavior seems better, in that it gives a little more information--you could implement the 3530 behavior using the posix behavior, but not the other way around. Also, the Linux client makes no attempt to remap this error in the v4 case, so it can end up just returning EEXIST to the application in a case where it should return EISDIR. So honestly I think the rfc's are just buggy here--or in any case it doesn't see worth the trouble to remap this error. Reported-by: Frank S Filz <[email protected]> Signed-off-by: J.

2013-04-30f2fs: modify the number of issued pages to merge IOsJaegeuk Kim3-5/+14
When testing f2fs on an SSD, I found some 128 page IOs followed by 1 page IO were issued by f2fs_write_node_pages. This means that there were some mishandling flows which degrades performance. Previous f2fs_write_node_pages determines the number of pages to be written, nr_to_write, as follows. 1. The bio_get_nr_vecs returns 129 pages. 2. The bio_alloc makes a room for 128 pages. 3. The initial 128 pages go into one bio. 4. The existing bio is submitted, and a new bio is prepared for the last 1 page. 5. Finally, sync_node_pages submits the last 1 page bio. The problem is from the use of bio_get_nr_vecs, so this patch replace it with max_hw_blocks using queue_max_sectors. Signed-off-by: Jaegeuk Kim <[email protected]>

2013-04-29fat (exportfs): rebuild directory-inode if fat_dget()Namjae Jeon4-2/+78
This patch enables rebuilding of directory inodes which are not present in the cache.This is done by traversing the disk clusters to find the directory entry of the parent directory and using its i_pos to build the inode. The traversal is done by fat_scan_logstart() which is similar to fat_scan() but matches i_pos values instead of names.fat_scan_logstart() needs an inode parameter to work, for which a dummy inode is created by it's caller fat_rebuild_parent(). This dummy inode is destroyed after the traversal completes. All this is done only if the nostale_ro nfs mount option is specified.

2013-04-29fat: introduce 2 new values for the -o nfs mount optionNamjae Jeon2-9/+21
This patchset eliminates the client side ESTALE errors when a FAT partition exported over NFS has its dentries evicted from the cache. The idea is to find the on-disk location_'i_pos' of the dirent of the inode that has been evicted and use it to rebuild the inode. This patch: Provide two possible values 'stale_rw' and 'nostale_ro' for the -o nfs mount option.The first one allows all file operations but does not reduce ESTALE errors on memory constrained systems. The second one eliminates ESTALE errors but mounts the filesystem as read-only. Not specifying a value defaults to 'stale_rw'.

Walking a bio's page mappings has proved problematic, so create a new bio flag to indicate that a bio's data needs to be snapshotted in order to guarantee stable pages during writeback. Next, for the one user (ext3/jbd) of snapshotting, hook all the places where writes can be initiated without PG_writeback set, and set BIO_SNAP_STABLE there. We must also flag journal "metadata" bios for stable writeout, since file data can be written through the journal. Finally, the MS_SNAP_STABLE mount flag (only used by ext3) is now superfluous, so get rid of it.

Currently, dio_send_cur_page() submits bio before current page and cached sdio->cur_page is added to the bio if sdio->boundary is set.

2013-04-29direct-io: fix boundary block handlingJan Kara1-1/+2
When we read/write a file sequentially, we will read/write not only the data blocks but also the indirect blocks that may not be physically adjacent to the data blocks. So filesystems set the BH_Boundary flag to submit the previous I/O before reading/writing an indirect block. However the generic direct IO code mishandles buffer_boundary(), setting sdio->boundary before each submit_page_section() call which results in sending only one page bios as underlying code thinks this page is the last in the contiguous extent. So fix the problem by setting sdio->boundary only if the current page is really the last one in the mapped extent. With this patch and "direct-io: submit bio after boundary buffer is added to it" I've measured about 10% throughput improvement of direct IO reads on ext3 with SATA harddrive (from 90 MB/s to 100 MB/s). With ramdisk, the improvement was about 3-fold (from 350 MB/s to 1.2 GB/s). For other filesystems (such as ext4), the improvements won't be as visible because the frequency of BH_Boundary flag being set is much smaller.

2013-04-29proc: Delete create_proc_read_entry()David Howells3-204/+1
Delete create_proc_read_entry() as it no longer has any users. Also delete read_proc_t, write_proc_t, the read_proc member of the proc_dir_entry struct and the support functions that use them. This saves a pointer for every PDE allocated. Signed-off-by: David Howells <[email protected]> Signed-off-by: Al Viro <[email protected]>

2013-04-29fs/block_dev.c: fix iov_shorten() criteria in blkdev_aio_read()Gu Zheng1-1/+1
blkdev_aio_read() test 'size' to see if it is equal or greater than the target count we request(iocb->ki_left). If so there is no need to call iov_shorten() to reduce number of segments and the iovec's length. So the judgement should be changed to 'if (size < iocb->ki_left)' instead.

2013-04-29NFSv4: Warn once about servers that incorrectly apply open mode to setattrTrond Myklebust1-0/+7
Debugging aid to help identify servers that incorrectly apply open mode checks to setattr requests that are not changing the file size. Signed-off-by: Trond Myklebust <[email protected]>
2013-04-29NFSv4: Servers should only check SETATTR stateid open mode on size changeTrond Myklebust1-4/+9
The NFSv4 and NFSv4.1 specs are both clear that the server should only check stateid open mode if a SETATTR specifies the size attribute. If the open mode is not one that allows writing, then it returns NFS4ERR_OPENMODE. In the case where the SETATTR is not changing the size, the client will still pass it the delegation stateid to ensure that the server does not recall that delegation. In that case, the server should _ignore_ the delegation open mode, and simply apply standard permission checks. Signed-off-by: Trond Myklebust <[email protected]>
