[PATCH] Fix up symlink function pointers

2005-08-20T01:08:21+00:00

This fixes up the symlink functions for the calling convention change:

 * afs, autofs4, befs, devfs, freevxfs, jffs2, jfs, ncpfs, procfs,
   smbfs, sysvfs, ufs, xfs - prototype change for ->follow_link()
 * befs, smbfs, xfs - same for ->put_link()

JFS: Fix race in txLock

2005-08-10T16:14:39+00:00

TxAnchor.anon_list is protected by jfsTxnLock (TXN_LOCK), but there was
a place in txLock() that was removing an entry from the list without holding
the spinlock.

JFS: Check for invalid inodes in jfs_delete_inode

2005-08-01T21:54:26+00:00

Some error paths may iput an invalid inode with i_nlink=0.  jfs should
not try to actually delete such an inode.

JFS: Improve sync barrier processing

2005-07-27T14:17:57+00:00

Under heavy load, hot metadata pages are often locked by non-committed
transactions, making them difficult to flush to disk.  This prevents
the sync point from advancing past a transaction that had modified the
page.

There is a point during the sync barrier processing where all
outstanding transactions have been committed to disk, but no new
transaction have been allowed to proceed.  This is the best time
to write the metadata.

JFS: Fix i_blocks accounting when allocation fails

2005-07-26T14:29:13+00:00

A failure in dbAlloc caused a directory's i_blocks to be incorrectly
incremented, causing jfs_fsck to find the inode to be corrupt.

JFS: Don't set log_SYNCBARRIER when log->active == 0

2005-07-25T13:58:54+00:00

If a metadata page is kept active, it is possible that the sync barrier logic
continues to trigger, even if all active transactions have been phyically
written to the journal.  This can cause a hang, since the completion of the
journal I/O is what unsets the sync barrier flag to allow new transactions
to be created.

JFS: fsync wrong behavior when I/O failure occurs

2005-07-15T15:36:08+00:00

This is half of a patch that Qu Fuping submitted in April.  The first part
was applied to fs/mpage.c in 2.6.12-rc4.

jfs_fsync should return error, but it doesn't wait for the metadata page to
be uptodate, e.g.:
jfs_fsync->jfs_commit_inode->txCommit->diWrite->read_metapage->
__get_metapage->read_cache_page reads a page from disk. Because read is
async, when read_cache_page: err = filler(data, page), filler will not
return error, it just submits I/O request and returns. So, page is not
uptodate.  Checking only if(IS_ERROR(mp->page)) is not enough, we should
add "|| !PageUptodate(mp->page)"
