 Description   

New struct mnt_idmap wraps user namespace struct and changes several inode_operations functions (getattr, setattr ...)

New header <linux/filelock.h> and also breaks locks_lock_file_wait() test.

struct kernel_cap_t changed from any array of u32s to a single u64 breaking several lustre apis.

Continue using the lower 32 bits to maintain compatibility:

As of linux commit v3.6-10973-g607ca46e97a1 lustre implicitly
started to ignore some capabilities, see: include/uapi/linux/capability.h
Last capability flag was added in linux commit v5.8-rc5-1-g124ea650d307
The capabilities the Lustre ignores are:

  • CAP_MAC_OVERRIDE
  • CAP_MAC_ADMIN
  • CAP_SYSLOG
  • CAP_WAKE_ALARM
  • CAP_BLOCK_SUSPEND
  • CAP_AUDIT_READ
  • CAP_PERFMON
  • CAP_BPF
  • CAP_CHECKPOINT_RESTORE
    None of which appear to be important to Lustre operations and should
    be fine to continue ignore.
