hfsplus: fix double lock typo in ioctl

2010-10-25T18:39:07Z

This was supposed to be a mutex_unlock() instead of a mutex_lock(). Signed-off-by: Dan Carpenter Signed-off-by: Christoph Hellwig

hfsplus: fix getxattr return value

2010-10-15T12:45:00Z

We need to support -EOPNOTSUPP for attributes that are not supported to match other filesystems and allow userspace to detect if Posix ACLs are supported or not. setxattr already gets this right. Signed-off-by: Christoph Hellwig

hfsplus: remove superflous rootflags field in hfsplus_inode_info

2010-10-14T13:54:33Z

The rootflags field in hfsplus_inode_info only caches the immutable and append-only flags in the VFS inode, so we can easily get rid of it. Signed-off-by: Christoph Hellwig

hfsplus: fix HFSPLUS_I calling convention

2010-10-01T03:43:31Z

HFSPLUS_I doesn't return a pointer to the hfsplus-specific inode information like all other FOO_I macros, but dereference the pointer in a way that made it look like a direct struct derefence. This only works as long as the HFSPLUS_I macro is used directly and prevents us from keepig a local hfsplus_inode_info pointer. Fix the calling convention and introduce a local hip variable in all functions that use it constantly. Signed-off-by: Christoph Hellwig

hfsplus: fix HFSPLUS_SB calling convention

2010-10-01T03:42:59Z

HFSPLUS_SB doesn't return a pointer to the hfsplus-specific superblock information like all other FOO_SB macros, but dereference the pointer in a way that made it look like a direct struct derefence. This only works as long as the HFSPLUS_SB macro is used directly and prevents us from keepig a local hfsplus_sb_info pointer. Fix the calling convention and introduce a local sbi variable in all functions that use it constantly. Signed-off-by: Christoph Hellwig

hfsplus: protect setflags using i_mutex

2010-10-01T03:41:35Z

Use i_mutex for protecting against concurrent setflags ioctls like in other filesystems and get rid of the BKL in hfsplus_ioctl. Signed-off-by: Christoph Hellwig

hfsplus: split hfsplus_ioctl

2010-10-01T03:41:31Z

Give each ioctl command a function of it's own. Signed-off-by: Christoph Hellwig

hfsplus: fix BKL leak in hfsplus_ioctl

2010-10-01T03:41:27Z

Currenly the HFSPLUS_IOC_EXT2_GETFLAGS case never unlocks the BKL, which can lead to easily reproduced lockups when doing multiple GETFLAGS ioctls. Fix this by only taking the BKL for the HFSPLUS_IOC_EXT2_SETFLAGS case as neither HFSPLUS_IOC_EXT2_GETFLAGS not the default error case needs it. Signed-off-by: Christoph Hellwig

hfsplus: Push down BKL into ioctl function

2010-05-17T03:27:03Z

HFS is one of the remaining users of the ->ioctl function, convert it blindly to unlocked_ioctl by pushing down the BKL. Signed-off-by: Arnd Bergmann Signed-off-by: Frederic Weisbecker

[PATCH] r/o bind mounts: elevate write count for ioctls()

2008-04-19T04:29:24Z

Some ioctl()s can cause writes to the filesystem. Take these, and make them use mnt_want/drop_write() instead. [AV: updated] Acked-by: Al Viro Signed-off-by: Christoph Hellwig Signed-off-by: Dave Hansen Signed-off-by: Andrew Morton Signed-off-by: Al Viro
