From 1751e8a6cb935e555fcdbcb9ab4f0446e322ca3e Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 27 Nov 2017 13:05:09 -0800 Subject: Rename superblock flags (MS_xyz -> SB_xyz) This is a pure automated search-and-replace of the internal kernel superblock flags. The s_flags are now called SB_*, with the names and the values for the moment mirroring the MS_* flags that they're equivalent to. Note how the MS_xyz flags are the ones passed to the mount system call, while the SB_xyz flags are what we then use in sb->s_flags. The script to do this was: # places to look in; re security/*: it generally should *not* be # touched (that stuff parses mount(2) arguments directly), but # there are two places where we really deal with superblock flags.
