Revert "fs: Convert bd_mount_sem to mutex" · 2fce95d0

Thomas Gleixner authored Jul 27, 2009

This reverts commit 2e272570.

hch muttered: "Actually we may return to userspace with it held, so
the conversion is a bad idea.  But I have a patch I need to post to
completely get rid of it."

xfs: Convert mr_lock, m_peraglock to rw_anon_semaphore · fa9298a5

Thomas Gleixner authored Jul 26, 2009

Both locks have no struct owner rules and therefor preempt-rt must
keep them as real semaphores. Convert them to rw_anon_semaphores and
annotate their semantics hereby.

fs: Convert i_alloc_sem to rw_anon_semaphore · 087498ee

Thomas Gleixner authored Jul 26, 2009

i_alloc_sem is used as a completion in direct-io which does not follow
owner rules. preempt-rt needs to keep it as such. So convert it to
rw_anon_semaphore and annotate the semantics hereby.

rw_semaphores: Add rw_anon_semaphores · 7715da0b

Thomas Gleixner authored Jul 26, 2009

Most of the rw_semaphores have struct owner semantics. i_alloc_sem and
two xfs ones are used as both semaphores and completions. That makes
it hard to convert for preempt-rt. Add an rw_anon_semaphores type
which is not converted on -rt.

semaphore: Remove mutex emulation · a15032a6
