2011-10-28CIFS: Fix oops while mounting with prefixpathPavel Shilovsky
commit f5bc1e755d23d022bf948904386337fc3e5e29a8 upstream. commit fec11dd9a0109fe52fd631e5c510778d6cbff6cc caused a regression when we have already mounted //server/share/a and want to mount //server/share/a/b. The problem is that lookup_one_len calls __lookup_hash with nd pointer as NULL. Then __lookup_hash calls do_revalidate in the case when dentry exists and we end up with NULL pointer deference in cifs_d_revalidate: if (nd->flags & LOOKUP_RCU) return -ECHILD; Fix this by checking nd for NULL.

[Rabin VINCENT] This is for I$-D$ coherence issues when bounce buffers are used for the MMC driver and code is executed from a file system on eMMC.

2011-07-21vfs: drop conditional inode prefetch in __do_lookup_rcuLinus Torvalds
It seems to hurt performance in real life. Yes, the inode will be used later, but the conditional doesn't seem to predict all that well (negative dentries are not uncommon) and it looks like the cost of prefetching is simply higher than depending on the cache doing the right thing. As usual. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-07-21FS-Cache: Fix __fscache_uncache_all_inode_pages()'s outer loopJan Beulich
The compiler, at least for ix86 and m68k, validly warns that the comparison: next <= (loff_t)-1 is always true (and it's always true also for x86-64 and probably all other arches - as long as pgoff_t isn't wider than loff_t). The intention appears to be to avoid wrapping of "next", so rather than eliminating the pointless comparison, fix the loop to indeed get exited when "next" would otherwise wrap. On m68k the following warning is observed: fs/fscache/page.c: In function '__fscache_uncache_all_inode_pages': fs/fscache/page.c:979: warning: comparison is always false due to limited range of data type Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Reported-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: David Howells <dhowells@redhat.com> Cc: Suresh Jayaraman <sjayaraman@suse.de> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-07-14GFS2: Resolve inode eviction and ail list interaction bugSteven Whitehouse
This patch contains a few misc fixes which resolve a recently reported issue. This patch has been a real team effort and has received a lot of testing. The first issue is that the ail lock needs to be held over a few more operations. The lock thats added into gfs2_releasepage() may possibly be a candidate for replacing with RCU at some future point, but at this stage we've gone for the obvious fix. The second issue is that gfs2_write_inode() can end up calling a glock recursively when called from gfs2_evict_inode() via the syncing code, so it needs a guard added. The third issue is that we either need to not truncate the metadata pages of inodes which have zero link count, but which we cannot deallocate due to them still being in use by other nodes, or we need to ensure that those pages have all made it through the journal and ail lists first. This patch takes the former approach, but the latter has also been tested and there is nothing to choose between them performance-wise. So again, we could revise that decision in the future. Also, the inode eviction process is now better documented.

2011-07-12GFS2: Fix race during filesystem mountSteven Whitehouse
There is a potential race during filesystem mounting which has recently been reported. It occurs when the userland gfs_controld is able to process requests fast enough that it tries to use the sysfs interface before the lock module is properly initialised. This is a pretty unusual case as normally the lock module initialisation is very quick compared with gfs_controld. This patch adds an interruptible completion which is used to ensure that userland will wait for the initialisation of the lock module to complete. There are other potential solutions to this problem, but this is the quickest at this stage and has been tested both with and without mount.gfs2 present in the system.

2011-07-12GFS2: force a log flush when invalidating the rindex glockBenjamin Marzinski
Right now, there is nothing that forces the log to get flushed when a node drops its rindex glock so that another node can grow the filesystem. If the log doesn't get flushed, GFS2 can corrupt the sd_log_le_rg list in the following way. A node puts an rgd on the list in rg_lo_add(), and then the rindex glock is dropped so the other node can grow the filesystem. When the node reacquires the rindex glock, that rgd gets deleted in clear_rgrpdi() before ever being removed from the list by gfs2_log_flush(). This code simply forces a log flush when the rindex glock is invalidated, solving the problem.
