Add FS_XFLAG_CASEFOLD to xfs_ip2xflags()\nwhen the filesystem is formatted with the ASCIICI feature\nflag. This serves both FS_IOC_FSGETXATTR (via xfs_fill_fsxattr() in\nxfs_fileattr_get()) and XFS_IOC_BULKSTAT (which populates bs_xflags\ndirectly from xfs_ip2xflags()), so bulkstat consumers and per-inode\nqueries see a consistent view of the filesystem's case-folding\nbehavior.\n\nXFS always preserves case. XFS is case-sensitive by default, but\nsupports ASCII case-insensitive lookups when formatted with the\nASCIICI feature flag.\n\nSigned-off-by: Chuck Lever \n---\n fs/xfs/libxfs/xfs_inode_util.c | 2 ++\n 1 file changed, 2 insertions(+)","diff":"diff --git a/fs/xfs/libxfs/xfs_inode_util.c b/fs/xfs/libxfs/xfs_inode_util.c\nindex 551fa51befb6..82be54b6f8d3 100644\n--- a/fs/xfs/libxfs/xfs_inode_util.c\n+++ b/fs/xfs/libxfs/xfs_inode_util.c\n@@ -130,6 +130,8 @@ xfs_ip2xflags(\n \n \tif (xfs_inode_has_attr_fork(ip))\n \t\tflags |= FS_XFLAG_HASATTR;\n+\tif (xfs_has_asciici(ip->i_mount))\n+\t\tflags |= FS_XFLAG_CASEFOLD;\n \treturn flags;\n }\n \n","prefixes":["v10","09/17"]}
