[PATCH 00/38] VFS: Convert trivial filesystems and more
Hi Al,
Here's a set of patches that:
(1) Provides a convenience member in struct fs_context that is OR'd into
sb->s_iflags by sget_fc().
(2) Provides a convenience vfs_init_pseudo_fs_context() helper function
for doing most of the work in mounting a pseudo filesystem.
(3) Converts all the trivial filesystems that have no arguments to
fs_context.
(4) Converts

[RFC PATCH 00/68] VFS: Convert a bunch of filesystems to the new mount API
Hi Al,
Here's a set of patches that converts a bunch (but not yet all!) to the new
mount API. To this end, it makes the following changes:
(1) Provides a convenience member in struct fs_context that is OR'd into
sb->s_iflags by sget_fc().
(2) Provides a convenience helper function, vfs_init_pseudo_fs_context(),
for doing most of the work in mounting a pseudo filesystem.

Recently, I got many reports about perfermance degradation
in embedded system(Android mobile phone, webOS TV and so on)
and failed to fork easily.
The problem was fragmentation caused by zram and GPU driver
pages. Their pages cannot be migrated so compaction cannot
work well, either so reclaimer ends up shrinking all of working
set pages. It made system very slow and even to fail to fork
easily.
