Subject: [PATCH 133/139] upcall: Allow md-cache to specify invalidations on
|
|
|
e7a346 |
xattr with wildcard
|
|
|
e7a346 |
|
|
|
e7a346 |
Currently, md-cache sends a list of xattrs, it is inttrested in recieving
|
|
|
e7a346 |
invalidations for. But, it cannot specify any wildcard in the xattr names
|
|
|
e7a346 |
Eg: user.* - invalidate on updating any xattr with user. prefix.
|
|
|
e7a346 |
|
|
|
e7a346 |
This patch, enable upcall to honor wildcard in the xattr key names
