This system call takes 5 arguments: fd - file descriptor of the directory flags - flags used by xstat mask - field mask used to request stat/xattr info buf - user buf to return collected info count - size of user buffer in bytes xgetdents() should read the directory entries, collect stat and xattr information for each entry as requested and return all the data back to the user in a container structure (linux_xdirent) as part of the supplied user buffer. Abhi Das (5): fs: xstat system call VFS bits fs: Add xgetdents system call and xreaddir file operation gfs2: Add a dynamic buffer backed by a vector of pages gfs2: Add sort functionality with extra parameter gfs2: Add xreaddir file operation and supporting functions arch/x86/syscalls/syscall_32.tbl | 3 + arch/x86/syscalls/syscall_64.tbl | 3 + fs/gfs2/Makefile | 3 +- fs/gfs2/dir.c | 80 +-- fs/gfs2/dir.h | 13 +- fs/gfs2/export.c | 2 +- fs/gfs2/file.c | 17 +- fs/gfs2/incore.h | 6 + fs/gfs2/inode.c | 3 +- fs/gfs2/inode.h | 5 + fs/gfs2/ops_fstype.c | 4 + fs/gfs2/sys.c | 26 +- fs/gfs2/util.c | 363 ++++++++++++++ fs/gfs2/util.h | 47 ++ fs/gfs2/xattr.c | 27 +- fs/gfs2/xattr.h | 23 + fs/gfs2/xreaddir.c | 1024 ++++++++++++++++++++++++++++++++++++++ fs/gfs2/xreaddir.h | 84 ++++ fs/readdir.c | 42 ++ fs/stat.c | 340 ++++++++++++- include/linux/fs.h | 5 + include/linux/stat.h | 16 +- include/linux/syscalls.h | 5 + include/uapi/linux/fcntl.h | 1 + include/uapi/linux/stat.h | 143 ++++++ 25 files changed, 2196 insertions(+), 89 deletions(-) create mode 100644 fs/gfs2/xreaddir.c create mode 100644 fs/gfs2/xreaddir.h -- 1.8.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
