* ceph: handle racing calls to ceph_init_dentrySage Weil2011-07-26
| | | | | | | | | | | | The ->lookup() and prepopulate_readdir() callers are working with unhashed dentries, so we don't have to worry. The export.c callers, though, need to initialize something they got back from d_obtain_alias() and are potentially racing with other callers. Make sure we don't return unless the dentry is properly initialized (by us or someone else).

* ceph: set dir complete frag after adding capabilitySage Weil2011-07-26
| | | | | | | | | | Curretly ceph_add_cap clears the complete bit if we are newly issued the FILE_SHARED cap, which is normally the case for a newly issue cap on a new directory. That means we clear the just-set bit. Move the check that sets the flag to after the cap is added/updated.

* ceph: fix ceph_lookup_open intent usageSage Weil2011-07-26
| | | | | | | | | | | | | | | We weren't properly calling lookup_instantiate_filp when setting up the lookup intent, which could lead to file leakage on errors. So: - use separate helper for the hidden snapdir translation, immediately following the mds request - use ceph_finish_lookup for the final dentry/return value dance in the exit path - lookup_instantiate_filp on success Reported-by: Al Viro <viro@ZenIV.linux.org.uk> Reviewed-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>

* ceph: fix bad parent_inode calc in ceph_lookup_openSage Weil2011-07-26
| | | | | | | | | | | | | | We were always getting NULL here because the intent file f_dentry is always NULL at this point, which means we were always passing NULL to ceph_mdsc_do_request. In reality, this was fine, since this isn't currently ever a write operation that needs to get strung on the dir's unsafe list. Use the dir explicitly, and only pass it if this open has side-effects that a dir fsync should flush. Reviewed-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>

* ceph: only queue capsnap if caps are dirtySage Weil2011-07-26
| | | | | | | | | | | | We used to go into this branch if i_wrbuffer_ref_head was non-zero. This was an ancient check from before we were careful about dealing with all kinds of caps (and not just dirty pages). It is cleaner to only queue a capsnap if there is an actual dirty cap. If we are racing with... something...we will end up here with ci->i_wrbuffer_refs but no dirty caps. Reviewed-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: fix snap writeback when racing with writesSage Weil2011-07-26
| | | | | | | | | | | | | | There are two problems that come up when we try to queue a capsnap while a write is in progress: - The FILE_WR cap is held, but not yet dirty, so we may queue a capsnap with dirty == 0. That will crash later in __ceph_flush_snaps(). Or on the FILE_WR cap if a write is in progress. - We may not have i_head_snapc set, which causes problems pretty quickly. Look to the snaprealm in this case. Reviewed-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>

| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | FS-Cache: Fix __fscache_uncache_all_inode_pages()'s outer loopJan Beulich2011-07-21
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

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.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
