Constant nc::types::FS_SECRM_FL

pub const FS_SECRM_FL: i32

Inode flags (FS_IOC_GETFLAGS / FS_IOC_SETFLAGS)

Note: for historical reasons, these flags were originally used and defined for use by ext2/ext3, and then other file systems started using these flags so they wouldn't need to write their own version of chattr/lsattr (which was shipped as part of e2fsprogs). You should think twice before trying to use these flags in new contexts, or trying to assign these flags, since they are used both as the UAPI and the on-disk encoding for ext2/3/4. Also, we are almost out of 32-bit flags. :-)

We have recently hoisted FS_IOC_FSGETXATTR / FS_IOC_FSSETXATTR from XFS to the generic FS level interface. This uses a structure that has padding and hence has more room to grow, so it may be more appropriate for many new use cases.

Please do not change these flags or interfaces before checking with linux-fsdevel@vger.kernel.org and linux-api@vger.kernel.org. Secure deletion
