2008-07-03sysfs: crash debuggingAndrew Morton
Print the name of the last-accessed sysfs file when we oops, to help track down oopses which occur in sysfs store/read handlers. Because these oopses tend to not leave any trace of the offending code in the stack traces.

2008-07-03sysfs: don't call notify_changeMiklos Szeredi
sysfs_chmod_file() calls notify_change() to change the permission bits on a sysfs file. Replace with explicit call to sysfs_setattr() and fsnotify_change(). This is equivalent, except that security_inode_setattr() is not called. This function is called by drivers, so the security checks do not make any sense.

2008-07-02Call fasync() functions without the BKLJonathan Corbet
lock_kernel() calls have been pushed down into code which needs it, so there is no need to take the BKL at this level anymore. This work inspired and aided by Andi Kleen's unlocked_fasync() patches. Acked-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2008-07-02Remove BKL from remote_llseek v2Andi Kleen
- Replace remote_llseek with generic_file_llseek_unlocked (to force compilation failures in all users) - Change all users to either use generic_file_llseek_unlocked directly or take the BKL around. I changed the file systems who don't use the BKL for anything (CIFS, GFS) to call it directly. NCPFS and SMBFS and NFS take the BKL, but explicitely in their own source now. I moved them all over in a single patch to avoid unbisectable sections. Open problem: 32bit kernels can corrupt fpos because its modification is not atomic, but they can do that anyways because there's other paths who modify it without BKL. Do we need a special lock for the pos/f_version = 0 checks? Trond says the NFS BKL is likely not needed, but keep it for now until his full audit. v2: Use generic_file_llseek_unlocked instead of remote_llseek_unlocked and factor duplicated code (suggested by hch) Cc: Trond.Myklebust@netapp.com Cc: swhiteho@redhat.com Cc: sfrench@samba.org Cc: vandrove@vc.cvut.cz Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2008-07-02[PATCH] ocfs2: fix oops in mmap_truncate testingColy Li
This patch fixes a mmap_truncate bug which was found by ocfs2 test suite. In an ocfs2 cluster more than 1 node, run program mmap_truncate, which races mmap writes and truncates from multiple processes. While the test is running, a stat from another node forces writeout, causing an oops in ocfs2_get_block() because it sees a buffer to write which isn't allocated. This patch fixed the bug by clear dirty and uptodate bits in buffer, leave the buffer unmapped and return. Fix is suggested by Mark Fasheh, and I code up the patch.

2008-07-02UBIFS: fix Zoltan's bugArtem Bityutskiy
Zoltan Sogor reported a bug. The following fails on UBIFS but does not fail on ext3. while true; do echo live for i in `seq 1 1000` do mkdir $i cd $i rmdir ../$i touch tmp &> /dev/null cd - &> /dev/null done; done; I am not sure is it a VFS bug/issue or not, but the reason of this is that 'touch tmp' has side effects. Namely, it causes ubifs_lookup(tmp) to be called which does not find the direntry (-ENOENT case) but hases it (d_add()), which cases d_count of parent direntry (the orphan) to be increased. Later on VFS open() call fails, but it does not put the orphan's dentry, so iput() does not happen and delete_inode() is not called. To heal this we just to not hash the dentry if the parent has i_nlink = 0. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
