similar to: [Patch] btrfs: use file_remove_suid() after i_mutex is held

V1 -> V2: Move kmalloc() before mutex_lock(), suggested by Arjan. file_remove_suid() should be called with i_mutex held, file_update_time() too. So move them after mutex_lock(). Plus, check the return value of kmalloc(). Signed-off-by: WANG Cong <amwang@redhat.com> Cc: Arjan <arjan@infradead.org> Cc: Chris Mason <chris.mason@oracle.com> Cc: Yan Zheng

V2 -> V3: set ''err'' to -ENOMEM when kmalloc() fails. Thanks to Tao.

Hello everyone, Btrfs v0.14 is now available for download. Please note the disk format has changed, and it is not compatible with older versions of Btrfs. For downloads and documention, please see the Btrfs project page: http://btrfs.wiki.kernel.org The oss.oracle.com Btrfs project page will soon start redirecting here. v0.14 has a few performance fixes and closes some races that could have

Having done a current checkout, creating a new FS and running iozone [1] on it results in an oops [2]. remove_suid is called, accessing offset 14 of a NULL pointer. Let me know if you''d like me to test any fix, do further debugging or get more information. Thanks, Daniel --- [1] # mkfs.btrfs /dev/sda4 # mount /dev/sda4 /mnt /mnt# iozone -a . --- [2] [ 899.118926] BUG: unable to

V1->V2: Check to see if our current ppos is >= i_size after a short DIO read, just in case it was actually a short read and we need to just return. This is similar to what already happens in the write case. If we have a short read while doing O_DIRECT, instead of just returning, fallthrough and try to read the rest via buffered IO. BTRFS needs this because if we encounter a compressed or

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In openSUSE 10.3, AppArmor modifies remove_suid to take a struct path rather than just a dentry. This patch tests that the kernel is openSUSE 10.3 or newer and adjusts the call accordingly. Debian/Ubuntu with AppArmor applied will also need a similar patch. Maintainers of btrfs under those distributions should build on this patch or,

The fault code has been calling file_update_time after ->page_mkwrite after it drops the page lock, but this is annoying because this calls mark_inode_dirty which can fail in Btrfs, so we want to be able to do these updates in ->page_mkwrite so we can get an error back to the user. So get rid of the file_update_time calls in the fault code and push it into everybody who has a

There is an error path in ocfs2_quota_write() that doesn't unlock &gqinode->i_mutex(). That seems unintentional. Found by smatch (http://repo.or.cz/w/smatch.git).
