f2fs: fix recursive lock by f2fs_setxattr

2014-06-02T13:13:16Z

This patch should resolve the following recursive lock. [] call_rwsem_down_write_failed+0x13/0x20 [] f2fs_setxattr+0x5c/0xa0 [f2fs] [] __f2fs_set_acl+0x1b9/0x340 [f2fs] [] f2fs_init_acl+0x4a/0xcb [f2fs] [] __f2fs_add_link+0x26e/0x780 [f2fs] [] f2fs_mkdir+0xb8/0x150 [f2fs] [] vfs_mkdir+0xb7/0x160 [] SyS_mkdir+0xab/0xe0 [] tracesys+0xe1/0xe6 [] 0xffffffffffffffff The call path indicates: - f2fs_add_link : down_write(&fi->i_sem); - init_inode_metadata - f2fs_init_acl - __f2fs_set_acl - f2fs_setxattr : down_write(&fi->i_sem); Here we should not call f2fs_setxattr, but __f2fs_setxattr. But __f2fs_setxattr is a static function in xattr.c, so that I found the other generic approach to use f2fs_setxattr. In f2fs_setxattr, the page pointer is only given from init_inode_metadata. So, this patch adds this condition to avoid this in f2fs_setxattr. Signed-off-by: Jaegeuk Kim

f2fs: split grab_cache_page and wait_on_page_writeback for node pages

2014-05-07T01:21:58Z

This patch splits grab_cache_page_write_begin into grab_cache_page and wait_on_page_writeback for node pages. This patch intends to enhance the latency to get node pages by alleviating unnecessary wait_on_page_writeback. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: avoid unneeded lookup when xattr name length is too long

2014-04-01T09:54:24Z

In f2fs_setxattr we have limit this attribute name length, so we should also check it in f2fs_getxattr to avoid useless lookup caused by invalid name length. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: avoid RECLAIM_FS-ON-W warning

f2fs: introduce fi->i_sem to protect fi's info

2014-03-20T13:10:11Z

This patch introduces fi->i_sem to protect fi's info that includes xattr_ver, pino, i_nlink. This enables to remove i_mutex during f2fs_sync_file, resulting in performance improvement when a number of fsync calls are triggered from many concurrent threads. Signed-off-by: Jaegeuk Kim
