Subject: [PATCH 0/8] Simplefs: group and simplify linux fs code
Date: Tue, 14 Apr 2020 14:42:54 +0200	[thread overview]
Message-ID: <20200414124304.4470-1-eesposit@redhat.com> (raw)

This series of patches introduce wrappers for functions,
arguments simplification in functions calls and most importantly
groups duplicated code in a single header, simplefs, to avoid redundancy
in the linux fs, especially debugfs and tracefs.

Signed-off-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>

Emanuele Giuseppe Esposito (8):
  apparmor: just use vfs_kern_mount to make .null
  fs: extract simple_pin/release_fs to separate files
  fs: wrap simple_pin_fs/simple_release_fs arguments in a struct
  fs: introduce simple_new_inode
  simplefs: add alloc_anon_inode wrapper
  simplefs: add file creation functions
  debugfs: switch to simplefs inode creation API
  tracefs: switch to simplefs inode creation API
