* performance/io-cache: fix double free.Raghavendra G2009-10-281-1/+1
| | | | | | | | | | | - the destroyer function passed to rbthash_table_init is used to free the data. The data being inserted is page and it is destroyed in ioc_page_destroy. Hence no destroyer function needs to be passed to rbthash_table_init. Signed-off-by: Anand V.

| | | | | | | | | | | | - readdir and readdir64 should not call same procedure booster_readdir in their implementation, since the layout of dirent structures returned by libc implementations of readdir and readdir64 is different (readdir returns struct dirent *, where as readdir64 returns struct dirent64 *).

* cluster/afr: Prevent spurious entry self-heal.Vikas Gorur2009-10-231-2/+13
| | | | | | | | | | | | | | If the initial lookup shows that 'pending' is positive, then self-heal will hold a lock and do a lookup again. This lookup might show that 'pending' is zero everywhere. However, entry self-heal used to consider this as a case of 'no sources' and try to merge the directories. This patch checks for that case and does not do the merge. Signed-off-by: Anand V.

There was a race condition in assuming that afr_sh_entry_impunge_parent_setattr_cbk will always return before impunge_xattrop_cbk and impunge_setattr_cbk. This patch fixes two additional problems: 1) Building the parent_loc from impunge_local->loc after STACK_WIND to impunge_xattrop_cbk has happened. In a simple afr-posix configuration the stack will have been destroyed by the time building of parent_loc is attempted. 2) parent_loc built in impunge_newfile_cbk was not being loc_wipe'd.
