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\nReviewed-by: Roland Mainz <roland.mainz@nrubsig.org>\nSigned-off-by: Chuck Lever <chuck.lever@oracle.com>\n---\n fs/xfs/libxfs/xfs_inode_util.c | 2 ++\n fs/xfs/xfs_ioctl.c | 7 +++++++\n 2 files changed, 9 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 \ndiff --git a/fs/xfs/xfs_ioctl.c b/fs/xfs/xfs_ioctl.c\nindex ed9b4846c05f..5a58fb0bad2b 100644\n--- a/fs/xfs/xfs_ioctl.c\n+++ b/fs/xfs/xfs_ioctl.c\n@@ -472,6 +472,13 @@ xfs_fill_fsxattr(\n \n \tfileattr_fill_xflags(fa, xfs_ip2xflags(ip));\n \n+\t/*\n+\t * FS_XFLAG_CASEFOLD is read-only; hide it from the legacy\n+\t * flags view so chattr's RMW cycle does not pass it back to\n+\t * xfs_fileattr_set().\n+\t */\n+\tfa->flags &= ~FS_CASEFOLD_FL;\n+\n \tif (ip->i_diflags & XFS_DIFLAG_EXTSIZE) {\n \t\tfa->fsx_extsize = XFS_FSB_TO_B(mp, ip->i_extsize);\n \t} else if (ip->i_diflags & XFS_DIFLAG_EXTSZINHERIT) {\n", "prefixes": [ "v11", "08/15" ] }
